s390: Deprecate ESA/390 support
Deprecate support for the ESA/390 architecture which will be eventually
removed, and encourage the usage of the z/Architecture instead.
Furthermore, default for -m31 to -mzarch whereas previously we defaulted
to -mesa.
gcc/ChangeLog:
* config.gcc: Fail in case of option --with-mode=esa.
* config/s390/s390.cc (s390_option_override_internal): Default
to z/Architecture mode.
* config/s390/s390.h (DRIVER_SELF_SPECS): Ditto.
* config/s390/s390.opt: Emit a warning for option -mesa.
* doc/invoke.texi: Document the change.
